SAFETY-RAZOR.

SPECIFICATION forming part. of Letters Patent N0. 7353,1599, dated J 14,1903.

Application filed February 19,1903. Serial No. 144,023. (No model.)

To (LZZ whom it may concern.-

Be it knownthat we, FREDERICK KAMPFE, RICHARD KAMPFE, and Orro KAMPFE,citizens of the United States, residing at the city of New York, in theborough of Brooklyn, county otKings, andState of New York, have inventedcertain new and useful Improvements in Safety-Razors, of which thefollowing is a specification.

This invention relates to improvements in safety-razors; and the objectof our invention is to provide a safety-razor of a novel constructionwhich can be readily opened up for the purpose of cleaning and wipingit, can readily be closed after such cleaning and wiping, renders theguard, guard-teeth, and entire interior of the casing very accessible,is simple in construction, and handy in use.

In the accompanying drawings, in which like letters of referenceindicatelike partsin all the figures, Figure l is a front view of oneconstruction of our improved safety-razor, the blade and blade-retainingclips being omitted and the casing being shown closed. Fig. 2 is an endview of the same in the same position. Fig. 3 is an end view of thesame, the casing being opened. Fig. i is an enlarged detail sideelevation of the pivot construction, the casing being open. Fig. 5 is asectional plan view on the line 5 5 of Fig. 4. Fig. 6 is a frontelevation of a modification of the construction, the casing beingclosed. Figs. 7 and 8 are end views of the same, closed and opened,respectively.

The razor-casing A of the conventional construction is substantiallyU-shaped in crosssection andis composed of a lower section B and anupper section E the lower section serving to receive the lather and theupper section serving to support the blade, which is not shown. Thelower section may be provided with a handle 0 of any desired shape orconstruction, the conventional rod-handle secured to the central part ofthe bottom section being here shown. So as to permit of opening up thecasing to fully expose the upper surface of the lower section and theunder surface of the upper section the two sections B and B areconnected with each other by a pivot or hinge connection D, soconstructed, mounted, and arranged that the upper section B can turn onthe lower section B in a plane extending from front to rear of thecasing the entire length thereof. As shown in the particularconstruction illustrated in Figs. 1 to 5, this hinged connection D isarranged at the center of the rear wall, so that the upper section turnson a central pivot on the rear wall of the lower section. In the normalposition the upper section eX- tends over the bottom section, as shownin Fig. 2, and when the casing is to be opened the upper section isturned on its pivot one hundred and eighty degrees, so that the uppersection now extends in the direction diametrically opposite to that inwhich it extended when over.

the lower section, as shown in Figs. 3 and 8. To close the casing, theupper section is swung back one hundred and eighty degrees into itsoriginal position. As shown in Figs. 1 to 5, a tubular part E is formedin the rear wall of the lower section at the top edge and a like part Ein the bottom edge of the rear Wall of the upper section, which tubularparts are in line, and a pivot F is held longitudinally in said tubularsections in such a manner that one of the sections can have a movementto a greater or less extent in the direction of the length of thepivot-that is to say, toward and from the other section. A helicalspring G surrounds this pivot in one or both tubular projections E andserves to draw the two sections B and B toward each other in thedirection of the length of the pivot. For the purpose of lockingthe'sections together, either when the casing is closed or when it isopened, one of the tubular projections is provided at the exposedend-that is, at the edge of the rear wall of the section-with atransverse beveled ridge or knife-edge H, parallel with and in line withthe edge of the said wall, and the other tubular projection is providedwith a corresponding groove J, parallel with and in line with the edgeof the rear wall of its section. The depths of said ridge and groove aresuch that when this ridge or knife-edge rests within this groove therear edges of the upper and lower sections will be in contact. When theupper section is turned for the purpose of opening or closing thecasing, the

inclined groove, and this separates the rear edges of the two sectionsslightly in the direction of the length of the pivot and holds ICObeveled ridge H rides upon the sides of the them apart until the uppersection has been turned one hundred and eighty degrees, and as soon asthe beveled ridge or knife-edge H is again in line with the groove J thespring G draws the edges of the rear walls of the two sections intocontact, and thus locks the parts against accidental displacement anduntil they are forciblydisplac'ed by turning one or theother on thepivot F. All that is hecessary to open the casing is to turn one sectionon the other one hundred and eighty degrees, and when such turn has beencompleted the two sections are automatically locked in relation to eachother'and in the positions in which they have been placed.

In the construction shown in Figs. 6, 7, and 8 the two sections 13 and Bare provided at their rear edges with lugs K, which may be formed byforcing out part of the metal or in any other suitable manner, whichlugs rest flat upon each other. Through these lugs the pivot I. ispassed, on which one section can be turned on the other in the mannerpreviously described. For the purpose of locking the two sections inplace the finger-latch M is pivoted to the inner surface'of the rearwall of the lower section near one side, and a stop N projects beyondthe bottom edge of the upper section at the opposite end of the casing.When the latch M is adjusted so as to release the upper section, onesection can be turned on the other in a plane extending from front torear sufficiently to open up the casing and guard and to permit theready removal of the lather both from the casing and guard by fullyexposing the upper surface of the bottom section of the casing and theunder side of the upper section, and thus permitting a thoroughly wipingand drying of all these parts in the most perfect manner. It should benoted that on account of the stop N the sections cannot be turned onehundred and eighty degrees when opened.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. A safety-razor having a casing formed of two sections which arepivotally connected to permit of turning one section in relation to theother in a plane intersecting the vertical transverse plane of thecasing, substantially as set forth.

2. A safety-razor, having a casing formed of an upper and lower section,which are pivotally connected to permit of turning one section inrelation to the other, in a plane extending in the direction from frontto the rear of the casing, substantially as set forth.

3. A safety-razor having a casing formed of an upper and lower section,which are pivotally connected to permit of turning one section inrelation to the other, in a plane extending in the direction from frontto the rear of the casing, and means for locking said sections in fixedpositions in relation to each other, substantially as set forth.

4. A safety-razor having a casing formed of an upper and lower sectionwhich are pivotally connected to permit of turning one section inrelation to the other, in a plane extending in the direction from frontto the rear of the casing, and means for automatically locking saidsections in fixed positions in relation to each other, substantially asset forth.

5. In a safety-razor, the combination with a lower section and an uppersection, the latter being provided with a guard, of a pivot connectionbetween said two sections, in the rear walls of said sections to permitof turning the sections in relation to each other in a plane extendingin the direction from front to rear of the casing formed by the twosections, substantially as set forth.

6. In a safety-razor, the combination with a lower casing-section and anupper casingsection, the latter provided with a guard, of a pivotconnectionfor said two sections at the free edges of the rear walls ofsaid section, which pivot connection extends through a plane from thefront to the rear of the casing whereby one section can be turned on theother in a plane extending in the direction from the front to the rearof the casing, substantially as set forth. 7

7. In a safety-razor, the combination with a lower and upper section,the latter provided with a guard, of a pivot-support formed in the rearwall of each section, at the meeting edges, and a pivot passed throughsaid pivotsupports, substantially as set forth.

8. In a safety-razor, the combination with a lower and uppercasing-section, the latter provided with a guard, a tubularpivot-support being provided in the rear wall of each section, a pivotin said pivot-supports, and a spring surrounding said pivot and drawingthe two sections toward each other, substantially as set forth.

9. In a safety-razor, the combination with a lower and uppercasingsection, the latter provided with a guard, a tubular pivot-supportprovided in the rear wall of each section, one of said pivot-supportshaving a ridge at its free end and the other a groove, a pivotpin insaid pivot-supports on which pivot-pin one section can turn and can alsomove'in the direction of the length of the pivot-pin, and' a spring fordrawing the sections toward each other in the direction of the length ofthe pivot-pin, substantially as set forth.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, this 17th day of February,1903.
